Hey guys!
Just replaced the thermostat on my 03EB. Looked for signs of leaks after words, and heared a whistling sound by the battery. A small air hose is open and it sucks air. Seems to be broken off from a rubber attatchment, but can’t figure it’s purpose. It goes to a two way splitter, and continues to a sensor of some sort - and to the air intake and ac as far as I can tell. Tried to cover the hole with a finger and it seems the engine settles down on idle, and the exhaust seems to have a different look with less smoke. Runs cleaner. May be my imagination. Does anyone know if it is supposed to be open like it is - or if is meant to be connected somewhere? Added a few pictures. One has the Ford part code I think.
Thanks in advance from Norway.
